Sorry, I meant remove the configurability check of the
"getOwnPropertyDescriptor" and "getPropertyDescriptor" trap return
values, and add a check as to whether the "defineProperty" trap return
value is an object to fix the property to.

How about *optional* property fixing as a compromise? We could
replace the configurability check of the "defineProperty" trap return
value with a check of whether the return value is an object, in which
case it would be treated as a property descriptor to fix the property
to, otherwise the return value would just be ignored.
If you replace the compulsory configurability check with an opt-in (by
choosing a particular return value to defineProperty trap), then
"optional property fixing" means "no property fixing", because the
optional part could be implemented as a library on top of proxies
without configurability check.
